one 99 19 Application filed February 26, 1512. Serial No. 630,115

To all or 710m it may concern Be it known that 1, Hour; J. Monmoutan a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Telephone-Directory of which the followin is a specification.

The object of my invention is to provide a spring actuated roller made of few parts are inexpensive in construction and that may be readily and easily assembled and that is provided with simple and inexpeir sivc means whereby a. telephone directory strip of paper, cloth or other suitable material may he quickly and. easily attached to or detached therefrom, which spring roller will automatically wind up the directory strip when the latter isreleased.

A further objectis to provide an improved bracket for supporting the roller so arranged that it may be quickly and easily applied to a telephone instrument by the simple operation of removing the receiving mouth iece of a tele hone instrument then placing the bracket adjacent to the telephone instruineI-it and returning the mouth piece .to position for firmly clamping the bracket.

A further object is'to provide improved means for stopping the winding movement of the directory strip upon the spring roller when the directory strip is fully wound up, which means is so arranged that it may be connected to the directory strip quickly and easily and WlllCll also so arranged that the lower end of the strip will not be torn or worn out by the repeated rolling up of the strip upon the spring roller.

My invention consists in certain details, in the construction, arrangement and com-- bination of the various parts of the device, whereby the objects contemplated are attained, ashereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which;

Figure 3. shows a front elevation of a part of a telephone instrument having my improved directory applied thereto and shown in its rolled up condition. Fig. 2 shows a side elevation. of same. Fig. 3 shows a front View of the telephone. directory embodying my invention detached from a telephone in struinent, and also shtfws the directory strip partially unwound from the roller. Fig. 4

F 1g. fishdws an e 'larged, detail, transverse, sectional view throughthe spring roller-"Fig. shows" a front elevation of the spring roller and its supporting bracket with the directory strip detached. Fig. 7 shows a front view of the upper portion of a directory strip designed opening 12 t erein. The arm 11 is formed flat and is designed tohe placed flat against the face of thereceiver portion of a telephone. This part of a telephone is indicated by the numeral 13. The circularopening 12 is of a size and shape to receive the "screw threaded portion of the transmitter mouth piece it of tlietelepiione which, when screwed into position in theordinaryway,

will bindthe arm 11 tightly against the face of the telephone. At the ends or" the body portion 10 are two forwardly extended arms 15 and 16 at right angles to "the body portion 10 and which is provided with an'angular opening 17.. The said arms 15 and 16 being niadelof spring filetll'ilitty be readily and easily sprung apart a slight distance and will then return to their normal positions at right angles t thc body portion 10.

Thespring' roller comprises a shaft 18 having angular en ls lQWhicli are designed to fit into the angular openings 17. The central portion oi the shaft preferably smooth and round and near; the end -portions of the shaft Efhave rotatably mounted two disks, each of which'comprises a" body portion 20, and an. outwardly extended flange 21. Each of said body portions 20 is provided .on its periphery with an annular grooveat 22 for purposes hereinafter made clear.

Coiled upon th central portion'of the spring having one end and at 24 to the shaft 18 and the other. end fixed to one of shaft 18 between the body portions 20 is a the body portions 20 at the point indicated by the numeral in Fig. 8. The body portion of the springroller isfornied of a single piece of spring sheet metal of substantially cylindrical form and indicated by the numeral The edges of the roller thus formed stand spaced apart from each other, as clearly shown in Fig. 6, and one edge is provided with a series of pointed lugs 27 wranged on the same curvature as the body portion of the cylinder, as clearly shown in Fig. 5. 'lhe end portionsot the cylinder 26 are provided with inwardly extended portions 28. These inwardly extended portions :28 are designed to enact with the annular grooves 22 in such a manner that when the cylinder 26 is sprung apart it may readily be placed with the parts 28 in the grooves 22 and then the resiliency of the metal will draw, the parts together, thus firmly holding the cylinder 26 to both of the bodyport-ious 20 and thereby preventing spre ading movements of the-body portions 20 toward or from each other. This yielding engagement between the cylinder and the body portions 20 also serves to firmly connect said parts in such a manner that they will all rotate in unison on the shaft 18.

Obviously the parts just described may be readily and easily assemble on the shafts 18 without the necessity or using rivets, bolts or similar tastening devices. Then the arms 15 and 16 may be sprung apart to thereby permit the angular ends of the shafts 18 to enter the angular openings 17. T hen when the arms 15 and 16 spring together all said parts will be lirmly united as required; for use.

The directory strip is formed of a single piece of paper, fabric, or the like indicated by the numeral. 29. At; its upper end are a number of slots 30 and its lower end is formed. into a loop-.31, as shown in Fig. 9. I attach the directory sheet to the spring roller by simply inserting the slotted end thereof in the open side of the cylinder and then permitting the projections 27 to pass through the slots 30, whereupon the remainder of the directory sheet is wound upon the spring roller in theprdinary manner.

At the bottom of the directory sheet, I

-have provided a handle and stop device comprising a hat sheet metal body portion 32 having upwardly extended arms 33 at its ends designed to project beyond the side edges of the directory sheet. These arms are provided with loops 34. in which I havedetachably mounted a rod 35. This rod is extended through the loop 81. The said arms 33 are so arranged and shaped that when the directory strip rolled up by the spring roller they will strike upon the arms 15 and 16 ot the bracket and thus limit themolling up movement of the directory :strip and at the same time receive all at the shock or jar, thus preventing the unnecessary wear or strain upon the directory strip that might otherwise be occasioned by means of stop devices or handles fixed to the directory strip by being inserted through openings formed therein. \Vith this construction there is obviously slight probability of tearing the directory strip or roller.

In practical use, it is obvious that my improved telcphonc directory may readily and quickly be applied to a telephone instrument in a firm and secure manner without any fastening devices other than are ordinarily provided on telephone instruments that have detachable screw threaded transmitter mouth pieces. The spring roller is of extremely simple construction and the Darts may all be readily assembled without the use of bolts, rivets, or other fastening devices. roller are assembled, the roller and shaft may be readily and easily inserted in the bracket and there lirmly held merely by the resiliency of the arms 15 and 1(3 and by having the squared ends of the shaft insert; ed in the squared openings of the said arms.

The directory strip is of extremely simple and inexpensive construction and has no fastening devices or the like applied to it.

doubled over and pasted or sewed together to form a loop. The upper end of the rectorystrip is made readily and easily tachable by simply inserting the end in open side of the roller and permitting the lugs 27 to enter the slots 30. Then it is rolled up in the ordinary way and the lower end is connected to the handle or stop device by inserting the rod 35' through the loop.

The entire device is constructed to be used without a ratchet device of any kind which is unnecessary for the reason that when the operator desires to read the matter upon. a directory striphe simply grasps the handle 32 and pulls the directory strip out until the desired information is attained. He then releasosthe handle and the directory strip automatically rolls up to its closed position, as shown in Fig. 1.

Before placing the directory strip upon the spring roller the operator simply turns the roller by hand a suitable number of revolutions until the spring 23 is put under a proper tension. He then attaches the directory strip and thereafter each time that the strip is pulled out a certain additional amount of aower is stored in the spring which is so icient to autmnatically rcwiud the directory strip when the handle. is roleased. The flanges 2] on the spring roller serve as guides to hold the directory strip firmly in line and the arms 2 3 at the ends of the handle or stop device, when they engage the arms 15 and .lli, will cause the dididethe After the parts of the spring der will m p sltlon arm" I idling said lgnlm" ends 5193i
